A Comparative Study of Machine Learning and Traditional Techniques for Grade Prediction and Grade-Tonnage Evaluation in a Small VMS Deposit
… Vulcan, and grade estimation was performed using Inverse Distance Weighting (IDW), Simple Kriging (SK), Ordinary Kriging (OK), and ensemble tree models. Traditional methods were assessed using cross-validation within Vulcan, while machine-learning models were evaluated using an independent …

Spatial precipitation trends and effects of climate change on the Hawai'ian Hualalai aquifer
… was then compared with spatial interpolation by inverse distance weighting (IDW) and ordinary kriging to assess the differences in methods. Results from the integrated spatial analysis show an annual decrease of -8.42 x 10⁶ m³/year across the entire study area and a decrease of -4.62 x 10⁶ …

Never Smokers -- Are They More Sensitive to the Respiratory Health Effects of Ambient Air Pollution?
… physical exercise, and dietary patterns. Inverse distance weighting (IDW) with interpolation to residence address was used to estimate individual level ambient air pollution. Cumulative monthly and averages from 12 months prior to enrollment until one month before censoring were used.</p> …

Assessing sustainable water, energy and food nexus smart innovations, technologies and practices in Luvuvhu and Nzhelele River catchments areas, Vhembe District Municipality, Limpopo province, South Africa.
… response frequencies. Additionally, the ArcGIS Inverse Distance Weighting (IDW) spatial interpolation method was employed for spatial analysis. The results indicated that the sustainability of the water-energy-food (WEF) nexus depends on the resilience of each resource individually as well as …

Development of national extent terrain attributes (TANZ), soil water balance surfaces (SWatBal), and environmental surfaces, and their application for spatial modelling of Pinus radiata productivity across New Zealand
… forward spatial interpolation technique, inverse distance weighting (IDW), were compared with those derived using the more complex RK, OK, and PLS techniques. Cross validation showed that all techniques performed better than their respective data means. OK, RK, and IDW techniques were …

Evaluation of Spatial Interpolation Techniques Built in the Geostatistical Analyst Using Indoor Radon Data for Ohio,USA
<p>According to the United States Environmental Protection Agency, radon is the number one cause of lung cancer among non-smokers, and it is responsible for about 21,000 lung cancer deaths every year in the United States. In the State of Ohio, 14% of lung cancer deaths are caused due to radon. It …
